Summary
This study found that most posts used to restore endodontically treated teeth had errors. Improving post restorations requires careful preparation to avoid damaging remaining tooth structure.
Area of Science:
- Dentistry
- Endodontics
- Prosthodontics
Background:
- Restoring endodontically treated teeth often requires intraradicular posts.
- The choice and placement of posts significantly impact restoration success.
Purpose of the Study:
- To evaluate the incidence of intraradicular retention.
- To determine the prevalence of different post types in clinical practice.
- To assess the quality and correctness of post restorations.
Main Methods:
- Analysis of 94 digital panoramic radiographies.
- Identification and assessment of root canal fillings and posts.
- Evaluation of morphologic parameters: length, diameter, and configuration.
Main Results:
- 224 out of 474 endodontically treated teeth were restored with posts.
- Cast posts (69.6%) were most common, followed by prefabricated non-metallic (24.6%) and metallic (5.8%) posts.
- A high error rate (84.37%) was observed in post manufacturing, selection, or application, linked to disregarded morphologic parameters.
Conclusions:
- Post preparation for endodontically treated teeth is beneficial if it preserves tooth structure.
- Optimal methods for restoring non-vital teeth remain a subject of scientific discussion.

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
